Feral Cats are in the same boat as you Rogues. RPPM trinkets, even at heroic, don't beat out Vicious Talisman + heroic double-upped Bottle. Or at least that's the simcraft results I saw posted. Sad sad times.
I'm not sure how Hunters pick their trinkets. I've read some pretty conflicting reports. Some people list heroic Talisman of Bloodlust + Heroic Bad Juju as the bis trinkets but it looked like they did that just based on item levels. Others have posted sim results that indicate that the Vicious Talisman + heroic double-upped Terror in the mists remains BiS for BeastMasters. Either way I haven't got a clue. One of our hunters should probably post about it so we know who's got a hard-on for which trinket.
For Enhance Shams, it's very very decisively Talisman of Bloodlust + Bad Juju even in normal modes. You have to stack the ever-living shit out of your haste, and it also basically locks you into taking Ancestral Swiftness as your Tier 4 talent, but in the end you can push the buff uptime to outrageous levels. In tier 15 gear, with something like 13k Haste Rating on unbuffed gear, you're looking at a 1.5x multiplier from Flurry and another 10% passive haste from AS talent before any raid buffs kick in. Ironically, Talisman of Bloodlust also scales with itself because the stacking haste will drive its own RPPM up. You end up with upwards of 40% uptime on Bad Juju as a result of this.
Primal Elementalist talent also got buffed this patch, and the fire elemental benefits the most from haste. You end up with a situation where your elemental cooldown (glyphed) starts amounting to literally a quarter of your entire DPS. Unfortunately, Simcraft is still ranking Enhancement at like middle-of-the-pack and even closer to the bottom in Tier 15 gear but their hardcoded ability priorities are broken as fuck given the talent changes in 5.2. When they get around to fixing that permanently, pretty sure Enhance is gonna start ranking pretty high up.
